This interactive graphic shows the areas of the UK where Brexit could hit hardest

LONDON — Brexit is undeniably one of the biggest events in recent
British history.

Over the course of the next few years the UK's entire
relationship with the rest of Europe is likely to be totally
reshaped.

Nowhere is that more true than in British industry, where firms
are almost certain to have to adjust to life outside the European
Single Market and to an entirely new trading relationship with
what is for most industries, their biggest trading partner.
